DISCOTIC MESOPHASES OF DIRHODIUM TETRACARBOXYLATES

The synthesis of dirhodium tetraoctaonate and dirhodium tetradodecanoate is described.Both complexes exhibit a thermotropic discotic mesophase that was characterized by optical microscopy, differential scanning calorimetry, and X-ray diffraction.A two-dimensional hexagonal columnar lattice was observed in which each column is made of stacked metal-metal bonded dirhodium units with a period of ca. 4.6 Angstroem.

Synthesis method capable of realizing mass production of rhodium octanoate dimer

The invention discloses a synthesis method capable of realizing mass production of rhodium octanoate dimer. The synthesis method is characterized by comprising the following steps: adding an alkalinesolution into certain amount of octanoic acid to adjust the pH value to 4.0-6.5; adding an aqueous solution of rhodium chloride; heating to certain temperature and cooling naturally; after the temperature is reduced to certain temperature, adding the alkaline solution to adjust the pH value to 9-13; stirring, filtering and washing with hot water for three times; after the product is cooled, washing twice with cold ethanol water, and drying to obtain grass-green rhodium octanoate dimer. The synthesis method of rhodium octanoate dimer disclosed by the invention has the advantages of high stability, high yield (larger than 97%), high product purity (larger than 99%) and obvious economic and environment-friendly benefits.
